Description

Project Description

The present problem simulates the heat transfer process inside a vertical helical shell and tube heat exchanger using ANSYS Fluent software. This type of heat exchanger consists of a vertical cylindrical shell with a spiral tube inside. The hotter part of the heat exchanger is related to the spiral tube of the heat exchanger, and the colder part is related to the shell of the heat exchanger. Hot water flow with a speed of 3.34 ms-1 and temperature equal to 350 K from the upper part of the heat exchanger enters the spiral tube, and cold water flows with speed equal to 0.216 ms-1 and temperature equal to 300 K from the upper part. The transducer enters the inner space of the shell. This work aims to investigate the heat transfer process between the two sides of the heat exchanger.

Heat Exchanger Geometry & Mesh

The present model is designed in three dimensions using design Modeler software. The model is a shell-tube heat exchanger with spiral tubes designed vertically. The cylindrical shell of the thermal model has a height of 500 mm and a diameter of 60 mm, and the spiral tube inside the shell has a diameter of 3 mm, and its step of the screw around the central axis of the shell is equal to 18 mm.

We carry out the model’s meshing using ANSYS Meshing software. The mesh type is unstructured. The element number is 3915382. The following figure shows the mesh.

Heat Exchanger CFD Simulation

We consider several assumptions to simulate the present model:

  • We perform a pressure-based solver.
  • The simulation is steady.
  • The gravity effect on the fluid is ignored.

Results & Discussions (Heat Transfer)

At the end of the solution process, two-dimensional and three-dimensional counters related to pressure, velocity, and temperature inside the heat exchanger are obtained. Two-dimensional contours are obtained on a plane passing through the center of the heat exchanger on both sides of the shell and the spiral tube. The results show that heat transfer is done between the two sides of the shell heat exchanger and the spiral tube, and the heat is from the hot part of the exchanger (spiral tube) to the cold part of the exchanger (shell).

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
